The egg cleaning and drying production line is the core equipment for the pre-treatment of egg processing. Its working process is designed around "efficient cleaning, thorough drying, and quality assurance", and it operates fully automatically. The specific steps are as follows:

Firstly, the egg products to be processed (such as fresh eggs and duck eggs) are evenly fed into the production line through an automatic feeding device, avoiding damage and accumulation caused by manual feeding. Subsequently, the eggs enter the pre-washing area, where a low-pressure spray system is used to spray clean water to initially wash away surface dust, stains and some sticky impurities, preparing for deep cleaning.

Next, we move on to the core cleaning area. The assembly line is equipped with a dual cleaning structure of brush rollers and high-pressure spray: the rotating brush rollers roll and rub against the surface of the eggs to remove stubborn stains and residual impurities on the eggshells. At the same time, high-pressure nozzles spray cleaning water that meets food-grade standards from multiple angles, powerfully peeling off dirt to ensure that the eggshells are clean without any blind spots. Some high-end equipment will add mild food-grade cleaning agents at this stage to enhance the cleaning effect, and then undergo a secondary rinse with clean water to avoid chemical residues.

After cleaning, the egg products enter the drainage area. Through the inclined conveyor belt and the air flow sweeping device, a large amount of water droplets adhering to the surface are quickly removed, reducing the energy consumption for subsequent drying. Then it enters the drying area. Inside the drying chamber, a constant-temperature hot air circulation system (with the temperature controlled at 40-60℃ to prevent high-temperature damage to the eggs) is used to continuously blow dry hot air. At the same time, it is slowly conveyed by a mesh belt to ensure that the surface moisture of the eggs is completely evaporated, achieving a dry and clean state.

Finally, the dried eggs are sorted by a sorting device to remove damaged and substandard products. The qualified eggs pass through the discharge port and enter the next processing procedure (such as grading, packaging, deep processing, etc.). The entire process is completed in a closed loop, which not only ensures the cleanliness of the eggs but also maintains the integrity of the eggshells and the freshness of the eggs.
